Red Bull Team Principal Christian Horner has hinted at rivals using "rubbery nose boxes" after a Technical Directive was introduced by the FIA ahead of the Singapore Grand Prix. Flexi-wings are at the centre of the latest TD, which will come into effect when F1 visits Marina Bay, with the sport's governing body aiming to clamp down on illegal use. Wings are permitted to flex given aerodynamic load would shatter components without an accepted level of movement, yet it is clear there has been ambiguity over that tolerance. Onboard cameras can show the top elements of front wings 'bending' under aerodynamic load down straights before reflexing back to state at lower speeds. Reacting to the directive, Horner insisted: "It's not something that affects us. "We've seen a few rubbery nose boxes, shall we say, so we'll see those get addressed, I guess, in Singapore."
FIA trust
Insisting there was no rule change enacted by the directive, Ferrari Team Principal Fred Vasseur explained: "By definition, a TD is a clarification of the regulation. "It means that there was already a regulation in place and we have to trust the FIA that, if they consider that they have to do the TD, it's probably that the regulation was not clear enough. "We trust the FIA in this direction to do that."
